Chemical constituents of Amygdalus spp. oil from Iran

Background and objectives: Amygdalus with a number of endemic species grow vastly in Iran. Edible sweet almond (A. communis), is cultivated in many countries due to its pharmaceutical, nutritional and cosmetic importance; while almond oil which is rich in oleic acid is known for its economic interest. In the present study, the amount and constituents of oil of six Amygdalu...

Chemical Constituents from the Stem Barks of Plumeria rubra L.

Background and objectives: Plumeria rubra L. (Apocynaceae) is a deciduous shrub or small tree cultivated in subtropical and tropical countries.  Its bark is prescribed to treat amoebic dysentery,   dropsy, jaundice, scabies, gonorrhea, venereal affections and wounds. In the present research, we aimed to isolate and identify the chemical constituents of the bark of ...

Chemical Constituents and Pharmacological Activity of Agarwood and Aquilaria Plants.

Agarwood, a highly precious non-timber fragrant wood of Aquilaria spp. (Thymelaeaceae), has been widely used in traditional medicine, religious rites, and cultural activities. Due to the inflated demanding and depleted natural resources, the yields of agarwood collected from the wild are shrinking, and the price is constantly rising, which restricts agarwood scientific research and wide applica...

Chemical Constituents from Euphorbia kansui.

In this research, a new triterpenoid, tirucalla-8,24-diene-3β,11β-diol-7-one (1), and eupha-8,24-diene-3β,11β-diol-7-one (2), which was isolated from Euphorbia kansui for the first time, together with twelve other known compounds (3-14), were isolated from the ethyl acetate extract of Euphorbia kansui. Their structures were elucidated based on High resolution electrospray ionization mass spectr...
